Abstract

Background:
Although fine-needle aspiration biopsy (FNAB) is considered the standard for preoperative evaluation of thyroid nodules, the value of this has been questioned for different thyroid nodules size. Different pathology and radiological scoring may improve the accuracy of preoperative diagnosis of thyroid nudoles. The aim of this study was to evaluate the relation between radiology Thyrads score and Bethesda pathology score system size in two group size (? 10 mm and > 10 mm) of thyroid nodule in US-FNAB.

Methods:
There were 183 thyroid nodules between 3 mm to 35 mm who underwent US-FNAB from January 2015 to November 2016 in Shaheed Sadoughi hospital- Yazd. They were divided in to two groups (group A, 3 - 10 mm; group B, 11- 35 mm). The patients were studied according radiology Thyrads score and Bethesda pathology score system. The relation between radiology Thyrads score and Bethesda pathology score system according groups size was analyzed by SPSS21.

Conclusions:
There was a statistically significance correlation between Thyrads score and pathologic Bethesda scoring system. Decision making basis on the radiologic Thyrads score can improve the radiological diagnosis precision in nodular goiter patients.
